This pressing machine-comprises cooperating pressing elements, onemovable toward and from the other, means for actuating themovable'element including apower member or lever, connections betweenthe power member andthe movable element including parts connected to themovable element and to the ower member, said parts being normally whenthe press is open and movable into effective relationby a preliminarymovement` ofthe movable element, a predetermined distance towards closedposition, [one 'vof' said ably the part associated with the powermember` being adjustableft'o. 'vary the extent'of the preliminaryclosing movement to the thickness of the work, that is', to vary thedistance Iremainingbetween the face of the movable element'or head and`th'e- 'face I of the xed element4 or buck at the end ofthe preliminaryclosing movement, and means for Iadjusting the pressure forworkofvdilerent l garment or 'laundry ing alower. pressiA 'ng'embodied'in" affv per movable pres'sin v element or head 2', theormerbeing mounte 5 upon a bracket 3 which is-mounted u on a table 4suitably supported by legs or pedidstals 5, 6, the leg being locatedcentrally of the rear side ofthe frame. The head 2 is usually carried onthe front arm ofa verticallymovable lever or yoke 7 pivoted at 8 betweenits ends to an upright 9 forming an extensionof the rear leg 6.'

The means for actuating the head ,2, inaddition to the head supportinglever 7, comprises a power member as a lever extending forwardly andrearwardly of the frame and movable vertically, this lever bein otedbetween-its ends at 11 to. the lower end of the rear leg 6, and motiontransmitting connections between the lever 10 and the rear armof thelever 7. These motion transmit- .ting connections include parts normallyar-` rangedout 'of effective .motion transmitting relation, when thepress is openand .movable into effectiverelation by a preliminary`closing movement of the press, a. predeter vmined distance towardclosed position, that is, by a preliminary movement ofthe head 2 vto aposition close to the buck 1 or the work on the buck. l Y' Thesemotiontransmitting connections as i here illustrated, comprise a toggleincluding links 12 and 13 pivoted together at 14 and a third linkassociated with the power lever, the link 12 bein arm of the lever7 andthe link 13 being pivoted to the frame, it being here .shown `as beingpivoted on the same pivot 11 on whichA the power lever 10 is mounted;thethird link 16 is pivoted at 17 to the rear arm of the pow-l erlever`10 and normally stands in nearly to the end of itspreliminaryclosing movefinally straightens the to ment is shown in Fig.3. This third` link acts'to thrust on one of the toggle links andvpartly straightened by the preliminary clos.-A -ing movement of thepress.

ln the illustrated embodiment ofmy invention, the link 12 is formed witha ver tical extension 13 extending beyond the point 14 ot3 the tog ie,this extension being normaliy spaced rom the thrust link and beingvbroiight into engagement with the thrust link-16 by the preliminaryclosing movement of the head 2. its here shown theextension is formedwith a shoulder 19 in the form of a notch at its lower end and the link16 is formed with an engaging end 20, the parts 19 and 20 being usuallyprovided on 'detachabie blocks which can be replaced when worn.

The thrust link 16 is held in its normal position by a nut 21 on a rodor bolt 22 se-l cured to the iframe on the web of the rear leg ii andsp" 23 interposed between the web l rust link16. By tui-ning the ieinitial angular position of the thrust iink 16 will be changed, andhence the space between the extension 18 and link. 16 varied. Thereforethe time with respect to the position of the head 2 that the linkpivoted at 15 to the rearA movement into effective relation` agie afterit' has been 12 comes into engagement with the thrust link will bevaried. By changing the relative angular position of the link 15 the eX-tent of the preliminary closing movement of the head 2 is adjusted tosuit the conditionsor the thickness'ofrf the work being op eratedupon.Thisv adjustingof the extentof the preliminary closing movement of thehead is to adjust the distance between the 1 pressing elements so thatthe head 2 will be so close to the work on the buck 1 at the end of thepreliminary movement, that it isimpossible for thev operator to'inserthis hands between the pressing elements or to eiectively apply the powerif his hand is between the pressing element during the preliminary-closlng movement.

The means for ladjusting the toggle to regulate the pressure withoutshifting the,

position of the head 2 to'vary the distance between the head 2 and thebuck 1 or the work thereon at the end of the preliminary closingmovement, comprises means by which the sections composing one of thetoggle links, as the toggle link 12, can be moved endwise relatively vtoeach other without .changing the length of the toggle link, that is,without varying the normal distance between the pivots 14 and 15.

In the illustrated embodiment of my invention, the link 12 `is composedof sections -havi`ng a slidinr movement when the pressure is appliedmeans forlimiting the sliding movement. As here illustrated, the link 12is composed of two sections designated generally, 25 and rom the powerlever 10 andl 26, the section 25 being formed with a lengthwise` guideor .bore 27 and the Section 26 comprising a rod having threads at itsopposite ends, the threads being in the same direction, that is, thethreads are either right i -hand or left hand, one end of the rodthreading in a head 28 which is mounted on the pivot 15 and the otherend threading through a head 29 slidable in the Guide v27 and held fromturning movement-iy'screws 30 cxltending'through slots 31 in the wallsof thc guide 27. The rod extends entirely throv'gn the head 29Aand hasits lower end arranged to engage an abutment 32 in the guide 27. Thisabutment may be the bottom of the bore, but is preferably a vbottoniplate supported by a comparatively stiff spring 33 interposed betweenthe plate andthe bottom of the bore. Therod is rovided with means forturning it as the w eel 35. y

The lowerend of the rod is normally spaced from the abutment 32. Uponturning of the rod it will unscrew from one of the parts 28, 29 andscrew into the other of said parts and hence the length of the link 12is not changed but. the distance between the end of the rod and theabutment 32 is varied. As the length of the link 12 is not varied, theposition of the head 2 is not changed. After the head has been-preliminarily closed so as to establish effectlve motion -transmittingrelation between the toggle and the thrust.

link 16 and power applied to the leverL'lO,

the link 12 will be moved upwardly durlng.

Preferabl a spring 36 is interposedbe# tween the sliding head l29 andthe abutmentv32 and hence thepressure applied before the rod 26 bottomson the abutment 32 will be equal to the pressure of the spring. Thesprings 36, or 36a of the. form shown in Figure 5, thrusts the rod 26upwardly and maintains the relative position of the press head, that is,it prevents the head from 4rising far eno-ugh to cause the rod 26 tobottom against the abutment 32 and also causes the pressure to be, firstyieldingly applied through the spring. In other words, the initial.position of the head is not varied. In any adjustment, it always startsfrom its same upward point. The gap between the head 2 and the work onthe buck 1 is varied, or the time at which the extension 18 of the link12comes into effective motion transmitting relation with the link 16is-determined, by the nut 21, that is, the extent of the preliminaryclosingof the head 5 from this constant starting position before thepower can be effectively applied is determined by the adjustment of thenut 2'1.

ln Fig. 5, the rod 261 is shown as being able i to bottom directly onthefbottom of the guide 36 as interposed between 27a, and the sprin theupper cnd of t e lower section a of the link and .the head 39 on' therod 26a, the head 39 being held in position by a nut 40 threading nn therod. The head 2 orthe supporting lever 7 is provided with a handle 41 atits front end for preliminarily'closing the' press and a weight isconnected to the rear arm of the lever 7 and also a spring 42both ofwhich aft to slightly overbalance the head 2, so that, the press opensunless the operator holds it preliminarily .closed until the ower isapplied to the power lever 10. 1n *igure 5, the

lower link of the toggle is formed with screws similar to the screws 30,which. screws thread into the block 25a and slide in slots 31 in thelower toggle link.

'l'he weight 43 is here shown as located on the front side of the axis 8of the lever 7 and is carried at the front end of the lever 44,

l pivoted at to a bracket 46 on the .rear side of the machine near thefloor and a link 48 connects a lever 44 and the rear arm of the lever 7.

'lhc means for actuating the power lever is here illustrated as an.intermittently movable shaft 49 having an eccentric or cam 50 on oneend coacting with a bearing face 51 on the power lever l0. the cam beingactuated intermittently sto maken half revolution during each actuation,by a constantly .running motor and a periodic or half revolution clutch'for. connecting and disconnecting the shaft 49 to the motor. 4

The shaft 49 is ournalled suitable bear# ings 53 and 54 in a housing 55carried bythe main frame of tliefmachine in any Isuit/able manner; andthe motorl 52 is also carriedby the frame in any suitable manner. Themotor is connected to the shaft 49 through a worm 52 mounted on anextension 52b of the armature sha-ft' of the motor, this worm 52ameshing with the worin gear 56, mounted to ro-l tate about the shaft 49.

' The periodic clutchl includes 'a shiftable section 57 ,mounted onandrotatable with the shaft 49 and shifta-ble axially of Lthe shaft, to

shift the clutch pins 58 into and out of holes y 59 in the worm gear 56.l i

In addition to the section 57 and the p-ins 58, the clutch includes adisk 60 rotatably mounted ,on the Shaft 49 and having guide openings`for ythe pins 58,1a pressure ring v61 interposed between the shiftablesection 57 f and the disk 60, a main spring 62 'interposed' .between'thedisk 60 and the section 574 and acting to throw the clutch outand-lighter springs 63 interposed betweenathe pressure ring 61l and thesection 57 and serving to 'l permit the pins to yield during theshifting in of thev clutch section 57 when the pinsare -7 heldin duringthe halfrevolution by a cam,

and is'automatic'ally thrust out by the'spring 62, the cam controllingthe, time atwhich thespring 62 is free to react.

The cam vis here shown 1n aring 70 fixed within the casing concentricwith the shaft 49 and having a planezfaee 71 and diametrically oppositenotches-72, the section 57 i io having followers 73 normallyarranged inthe notches and riding over'the .plane faces' when the clutchsection 57vhas been shifted inem'anually, the-plane faces holding the clutchsection 57 in. This clutch and cam construction forms no part of thisinvention.l

The clutch section 57- is shifted against the4 action of the spring 624by a shifter lever 74 A munted upon a rock shaft 75 which has ankupwardly projecting Vlever 77, a second rock shaft`78 mounted on theframe just below the table 4 and having a handle 79 atrits front end anda lever 8O between its ends coacting with the lever 77. .The rock Shaft75 is suitably mounted in the case 55 and the lever 74 y thrusts againstthe hub 76 of the section 57 .i The lever 8O isshaped to enclose thelever 77 and has a latch device 81 for coacting with a shoulder 82 onthe lever 77.- The construction is such that upon the depression of theree handit-...'79, tile nach s1 will engage the' shoul- 62 thrusts thesection 57 out and disengages.

der 81 and-throw the lever 77 to the right,

Figs. 6 and 7 ,causing the shifter lever 74 to thrust thesection 57 tothe left and the pins 58 to enter theholes 59 of constantly'running wormgear 56 and -thus clutch the shaft 49'to the worm wheel'56.

The 'shifting of the section the pins 58 Vfrom the wheel 56. The ends ofthe pins 58 and also the holes 59 are-tapered, so that, the pins readilydisengage themselves when there is no force applied to them, tending tohold them in the holes. 'At theA end ofthe depressing movementof thelever 79,

the latch 81 passes by the shoulder .82.andthus the operator byholdinghis'handjon the' lever 79 cannot cause the machinel to repeat. Y

less of the thlckness of the articles on the lower buck.

The latch 81 and the shoulder 82 are provided with suitableadjustingscrews 84 and 85 by which they can be positioned to coact mostefliciently. The movement of the power lever 10v downwardly` by theeccentric 50 is against the action of a suitable spring In operation,the press is vpreliminarlly vclosed preferably by pulling down onl thehandle 41 and then the handle lever 79 1s depressed to throw in theclutch, whereupon the shaft 49 makes a half revolutionintoits positionshown in Fig. 1, depressing the power lever' 10 and if the extension 18of' the tog-' gle link 12 has been brought into effective' motiontransmitting relation with the thrust -link 16 by the preliminaryclosing movement,

the motion 'of the lever 10 will be transferred .to thev toggle to causethe toggle to move near-V er a straightened position, that is, causingthe .joint 14 of the toggle to move in an upwardly and forwardly curvedarc thus applying ressure to the preliminarilyclosed press hea After thepress has'been closed as long as desired, the hand lever 7 9 is againdepressed again throwingl in the clutch causing the shaft 49 and theeccentric 50 to make another half` revolution from its position shown in'Fig 1, permitting the' counterweight and spring 42 to open the press.The spring 85 causes the power lever lllto follow the' cam 50. At theend each half revoution, as before stated, the follower 73 of the oiutchsection 5 7 comes into aline-ment with the notches 72 of the 78, sothat,'the spring 62 is free to 'throw .out the ciutch automatically.

In the event, the press iiead has not been preliminarily closed 'thedesired position, that is, 1n the event the head 2 not been 57 carriesthe followers `7 3 'out of the notches 72, and during' brought 'down soclose to the work on the lower buck 1 that Ythe operatoccannot have hishands or fingers on the work, the'powe'r lever 1Q will merely idle uponthe. depression of the handle lever 79 and the sequence of the machinelwill be upset andit will be necessary vto again depress the lever79-torestore the Sequence.

In the event the operator releasesthehan- I dle 41 before he operatesthe hand lever 73,

the head will open and hence, the power cannot be effectively applied. vf
